Windproof, water-resistant and warm, the Boys’ Nano Puff™ Jacket is an every-season stalwart, performing yeoman service as an outer layer in cool weather and as an insulating midlayer when things get really cold. Its tear-resistant fabric, made of 20-denier polyester mini-ripstop, has a DWR (durable water repellent) finish to shed rain. A carefully designed quilt pattern holds the lightweight and compressible 60-g PrimaLoft® Gold insulation in place for long-lasting wear. Zippered handwarmers (with reflective webbing pulls) and a tall collar provide additional protection. Other details include an internal wind flap behind the front zipper, spandex binding at the sleeve openings, adjustable drawcord hem, internal zippered chest pocket (that doubles as a stuffsack) and a hand-me-down ID label.

The windproof shell has high-tear strength and is made of polyester mini-ripstop with a DWR (durable water repellent) finish; fabric is bluesign® approved

Insulation

We use PrimaLoft insulation inside insulated garments for its warmth, compressibility, and soft comfort. While the human body uses energy to stay warm, PrimaLoft insulation uses a patented microfiber structure to help the body retain warmth and conserve energy.

The proprietary ultra-fine fibers of PrimaLoft insulation form a tight collection of air pockets that trap heat from your body and keep the cold out, providing an excellent warmth-to-weight ratio. When insulation gets wet, it loses these air pockets and consequently, its insulating properties. PrimaLoft ultra-fine fibers were developed to be water resistant so your insulation stays drier and maintains its insulating properties even when wet.

Water Resistant

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.
